s claims. (c1. 97-193) This invention relates to an improved weed hook for plows and more particularly to the mounting means for such weedl hooks. A Y. Various forms of weed hooks have been utilized heretofore to fold under tall grasses, weeds, or stubble when plowing so that the furrow slice will completely cover such vegetation. While these devices work with a reasonable'degree of satisfaction, many of them were cumbersome and of rather complicated construction resulting inI an expensive unit to produce. of these devices did not permit backing up of the tractor without serious damage to the weed hook.

Accordingly, it is an object of this invention to provide a simple and economically manufacturable mounting device for weed hooks for plows which permits limitedA pivotal movement of the Weed hook. v

A particular object of this invention is `to provide a weed hook mounting which may be fabricated in entirety by stamping operations on sheet metal. l

The specic nature of this invention, as well as vother objects and advantages thereon; will -become apparent to Vthose skilled in the art from the following detailed description, -takeninconjunction with the attached sheet of drawings on which, by vway of preferred example only, is illustratecl one embodimentof this invention. v On the drawings:

Figure 1 is a plan view'showinvg the weed hook mounted'on a plow beam. Figure 2 is a side view of Figure 1,. As shown on the drawings:

In Figure l there is shown in assembled rela- 'derneath'the curved portion of plow beam I3 as shown in Figure 2. Bracket I I 'is substantially wider than plow beam I3 and a notch IIbf'of the same width as beam I3 is provided in the rearend vof body portion IIa of bracket I I. The end-portions ll'c'adjacent notch IIb arebent-upwardly as shown in Figure 2 to lie against the-respective side surface of plow beam I3, and thus further anchor bracket II to the plow beam. A pair of spaced transverse holes IId are provided in the body portion I Ia of bracket I I and such holes are located adjacent the respective side surfaces of Furthermore, many 2 f plow beam I3 to admit the respective Ylegswofqllbolt I4. The washer Ida surrounding each leg ,of U-bolt I4 is placedadjacent the bottom surface of body portion I Ia Aand a nut I4b is threaded on to each end of U-bolt I4 whereby bodyportion IIa of bracket II vis secured tightly against'the underside of plow beam I3. y

An integral, horizontally disposed, forwardly projecting arm AI Ie is formed on body portion IIa as shown in Figures 1 and 2. AThe forward zedge I I f of arm IIe is arcuately shaped for apurp'ose to be later explained. 1 v

vAs previously mentioned; clevis Ill is pivotally Asecured to the forward end -of arm portion Ilge of bracket II by bolt I2.. Clevis I0 comprises a U- shaped stamping having an arcuate,4 forwardly disposed bight portion Ina. IIJa rotatably accommodates a cylindrical endV of a rod-like weed hook I5, such` weedhookl snugly but rotatably fitting within the bightportion of clevis I0. Weed hook I5 isA provided with a b ent end I5a formed at right angles to the axis ofthe cylindrical end of weed hook I5 and such bentend ts within a slot IDb provided in the;bight,por tion IUa near the upper edgeof` clevis 1I 0 as shown in .Figure 1. The bent end I5a oi weed hook-*I5 then lcooperates with the walls of slotlbgtogretain weed hookI5 against lateral displacement as Well as to limitjpivotal movement; of `weeduhook I5 to about 96%` A second weed hook I6 provided with reversely bent end IBa terminatingfin a cylindrical bearing portion I6b is rotatably mounted within clevis-11.0 adjacent weed hookyIlS, the bearing'portionV I Bb of weed hook I6 being disposed within clevis I0.

The' extreme end ofglovearing` portion I 6b vis vbent at right angles `asv-shown at IIcnWeed hook-'16 is mounted within'clevis I0 so thatv the; bent end LI 6c is disposed on the side of clevis v-I 0 -opposite togthat f of the bent end I5a of weed hook I 5. A portion-of the top part of clevis I0 is cut away 'toprovide .a shoulder Il'lc having an arcuate cornerj against which the upturned end I6'c of Weed 'hook .I 6 abuts whereby the pivotal movement of suchl weed hook is limited.' A tab Illd is providedon the bottom The bight portion rectangular member having a thickened transverse rib Ila on the forward edge thereof which traverses the space between the opposed walls of clevis I and abuts bearing portion |62) of weed hook I6. A similar but upwardly projecting rib I'lb is provided, on the back edge of spacer I'I which abuts the upper edge of clevis IIJ. The main body portion of' spacer I'Irests on top of bracket arm Ile and a vertically disposed hole I'Ic is provided in such spacer to receive bolt I2. A nut I2a and lock washer I2b are applied to bolt I2 but are not tightened suiiiciently to prevent pivotal movement ofl clevis ID about bolt I2.

Thus, the arm IIe and spacer I1 maintain the arms of U-shaped clevis I0 in properly spaced relationship. Transverse rib Ila is spaced somewhat from the arcuate end II ,f of arm I Ie to permit limited pivotal movement of clevis I0 about bolt l2.

-In some cases it maybe desirable to employ only asingle weed hook. The described mounting construction maybe conveniently employed in-such event by merely substituting a dummy piece'y for-the missing weed hook which conforms in configuration to the mounting end portion of the missing weed hook. lThe remaining weed hook will then be as securely positioned as before andwill function entirely independently on the substitution of the dummym'ounting portion of themissing Yweed hook.

Since .weed hooks I5 and I5 are freely pivoted as above described, the possibility of breakage of the tines when the tractor isbacked up without raising the plow bottom is minimized.rv Furthermore, the .pivotal movement of thev weedtines is ver-yfadvantageous when encountering some solid obstruction'in plowing, permitting the tines to slide up andover such obstruction. The limited pivotal movement of clevis IU about bolt I2 still `furtherprotects the tines against damage by permitting such tines to rotate slightly -as when lbacking upwhereby the-*tines will be in a'bett'er A`position to rotate upwardly and out of the vway. `From the foregoing description, it isV clearly 'apparent that-there is here provided a stamped bracket construction for mounting weed hooks on af-plow beam which 'is relatively inexpensive to produca-yet one which is of sturdy construction to withstand the hard usage such a device usual- 1y receives in plowing. The simple and vunique arrangement for limiting the pivotal movement .ofthe weed tines'isnot only positive in its oper-ation'4 but-.isf readily produced withoutA complicating `themanufacturingl operations.

It "will, ofcourse, be understood that various "details ofconstru'ction may be'varied through a -wide range without departing from the principles of this invention andit is, therefore, not the pur,-

pos'e to limit .the .patentgranted hereon other.- wise than necessitated by the scope .ofthe rappended claims. l
